Resource allocation

Abstract

Device, system and methods for flexible resource allocation are described. In particular, there is described a user receive a user equipment configured to receive higher-layer configuration of flexible resource allocation; receive dynamic information on the downlink resource allocation in a given downlink (DL) subframe; split the resource allocation into resource allocation sub-blocks; independently decode physical downlink shared channel (PDSCH) within each resource allocation sub-block; AND report ACK/NACK for the resource allocation.

The invention claimed is: 
     
       1. A user equipment (UE) comprising:
 receiver circuitry to:
 receive a higher layer configuration of flexible resource allocation; and 
 receive dynamic information on a downlink resource allocation in a given downlink (DL) subframe; 
 
 control circuitry to:
 divide the downlink resource allocation into resource allocation sub-blocks with boundaries of resource allocation sub-blocks on a serving layer in alignment with boundaries of resource allocation sub-blocks on an interfering layer; and 
 independently decode a physical downlink shared channel (PDSCH) within each resource allocation sub-block; and 
 
 transmitter circuitry to transmit an acknowledge/negative acknowledgment (ACK/NACK) for the downlink resource allocation. 
 
     
     
       2. The UE of  claim 1 , wherein the resource allocation sub-blocks within the downlink resource allocation are determined by the UE by monitoring two or more downlink control information (DCIs) with cyclic-redundancy control (CRC) scrambled by cell radio network temporary identifier (C-RNTI) for a DL component carrier. 
     
     
       3. The UE of  claim 1 , wherein a resource allocation sub-block size is determined in accordance with higher layer signaling. 
     
     
       4. The UE of  claim 3 , wherein the resource allocation sub-block size is equal to one or a multiple of a resource block group (RBG) size. 
     
     
       5. The UE of  claim 1  wherein the ACK/NACK for the resource allocation is determined by bundling of ACK/NACK reports across resource allocation sub-blocks. 
     
     
       6. One or more non-transitory, computer-readable media having instructions to cause a user equipment (UE), upon execution of the instructions by one or more processors of the UE, to:
 receive, from an evolved NodeB (eNB), an indication of a higher layer configuration of flexible resource allocation; 
 receive, from the eNB, an indication of downlink resource allocation for a downlink subframe in a radio frame; 
 identify a first resource allocation sub-block of the downlink resource allocation on a serving layer and a second resource allocation sub-block of the downlink resource allocation on an interfering layer, wherein boundaries of the first and second resource allocation sub-blocks are aligned; and 
 decode a first physical downlink shared channel (PDSCH) message within the first resource allocation sub-block and a second PDSCH message within the second resource allocation sub-block. 
 
     
     
       7. The one or more non-transitory, computer-readable media of  claim 6 , wherein the indication of downlink resource allocation is a dynamic indication of downlink resource allocation. 
     
     
       8. The one or more non-transitory, computer-readable media of  claim 6 , wherein the instructions, when executed, cause the UE to decode the first PDSCH message independent of the second PDSCH message. 
     
     
       9. The one or more non-transitory, computer-readable media of  claim 6 , wherein the instructions, when executed, further cause the UE to report an acknowledgement (ACK) message or a negative acknowledgement (NACK) message related to the downlink resource allocation. 
     
     
       10. The one or more non-transitory, computer-readable media of  claim 9 , wherein the instructions, when executed, further cause the UE to generate the ACK message or the NACK message based on bundling of ACK or NACK reports across the first and second resource allocation sub-blocks. 
     
     
       11. The one or more non-transitory computer-readable media of  claim 6 , wherein the instructions, when executed, further cause the UE to identify the first and second resource allocation sub-blocks based on monitoring of two or more downlink control information (DCI) messages having cyclic redundancy check (CRC) portions scrambled by a cell radio network temporary identifier (C-RNTI) for a downlink component carrier. 
     
     
       12. The one or more non-transitory, computer-readable media of  6 , wherein the instructions, when executed, further cause the UE to identify a size of the first or second resource allocation sub-blocks based on higher layer signaling. 
     
     
       13. The one or more non-transitory, computer-readable media of  claim 12 , wherein the size of the first or second resource allocation sub-block is equal to one or a multiple of a size of a resource block group (RBG). 
     
     
       14. An evolved NodeB (eNB) comprising:
 control circuitry to:
 schedule a flexible resource allocation for a user equipment (UE); 
 generate a first sub-block of the flexible resource allocation to be transmitted on a first layer and a second sub-block of the flexible resource allocation to be transmitted on a second layer, wherein boundaries of the first and second resource allocation sub-blocks are aligned; and 
 channel code within the first sub-block and the second sub-block wherein a channel coding of the first sub-block is independent of a channel coding of the second sub-block; and

       15. The eNB of  claim 14 , wherein the channel coding is related to a physical downlink shared channel (PDSCH) message.
